Cycledoggs custom trees - Graphical glitch

[The Bluejay 40]

As you can see, the largest clumps of tree's have turned into... somethings. No idea what those are.
It only happens with the largest clump size, only on this zoom level, and this appears to be the only thing affected. Any ideas?

What are your graphic settings?

Everythings on highest, and I'm using.... Software mode? Which ever the better one is. But I wouldn't have thought it was a graphic settings problem, everything else works perfectly and it happens only to the largest clump of trees.

Have you tried without any other plugins? Perhaps something else is conflicting with or over-riding the trees. Also, which set of Cycledogg's trees are you using? Might help to figure out what is causing the conflict (if one exists).
